Which of the following statements is true?
Blood glucose levels are controlled by the digestive system.
Damage to the kidneys will cause a buildup of waste in the body.
Oxygen is dropped off and picked up by blood vessels in the heart.
Digestion and breathing is controlled by the cerebrum.
Answer:
A for sure
Explanation:
Water has many of its properties and can act as a major liquid in our bodies due to its high specific heat. However, if water had a LOW heat capacity, its ability to serve as a liquid to maintain homeostasis would be altered. A student makes several claims about the impact the altered heat capacity would have on its properties. Which of these claims would NOT be supported by the change in specific heat capacity of water?
The claim which would not be supported by the change in specific heat capacity of water include reduction in body temperature and dehydration.
What is Specific heat capacity?This is defined as the quantity of heat needed to raise a substance's temperature by 1 degree Celsius.
If water has a low specific heat capacity then the body temperature will increase which will lead to an increase in dehydration.

Two brown-eyed parents have a child. The child has blue eyes.
Which term best describes the allele for the child's blue eyes?
If 'Two brown-eyed parents have a child and has blue eyes, then the term that best describes the allele for the child's blue eyes is recessive (option d).
What is a recessive gene allele variant?A recessive gene allele variant is any trait that is masked in heterozygous individuals due to the lack of expression of the allele, which is only expressed in homozygous individuals that has two copies of the same recessive alle (it can't be masked by the dominant allele in these individuals because we don't have this allele).
Therefore, with this data, we can see that a recessive allele variant is any gene variant capable of expressing one in homozygous individuals because it is masked by the dominant allele in heterozygous individuals who express the dominant allele.

what describes the genetic orders such as alkaptonuria and albinism.
Alkaptonuria (AKU) is a rare disorder of autosomal recessive inheritance. It is caused by a mutation in a gene that results in the accumulation of homogentisic acid (HGA). Characteristically, the excess HGA means sufferers pass dark urine, which upon standing turns black. This is a feature present from birth.
